Strange 'rstrip' error while importing tempest.scenario.test_server_basic_ops

[David Kranz]

I installed tempest on a clean machine as follows, both ubuntu and fedora:

1a. (fedora) sudo yum -y install python-pip git libxml2-devel libxslt-devel python-devel gcc openssl-devel
1b. (ubuntu) sudo apt-get install python-pip git gcc libxslt1-dev libxml2-dev python-dev zlib1g-dev
2. git clone http://github.com/openstack/tempest.git
3. cd tempest
4. sudo pip install -r requirements.txt
5. testr init
6. testr list-tests --> garbage due to import error

Then

ubuntu@ubuntu:~/tempest$ python -m tempest.scenario.test_server_basic_ops
2014-02-12 20:56:39.590 11694 CRITICAL tempest [-] 'NoneType' object has no attribute 'rstrip'

This is very strange. I also changed all rstrip to strip in the code so 'grep -r rstrip .' is clean, and still get the same error.
 Also:

>>> from tempest.common.utils import test_utils
>>> test_utils.ImageUtils()
2014-02-12 21:05:48.294 18172 CRITICAL tempest [-] 'NoneType' object has no attribute 'rstrip'

I tried adding -U to the pip install which required installing libssl-dev on ubuntu but the error is the same.

[David Kranz (david-kranz)]

After much pain I discovered that this problem is because importing tempest.scenario.test_server_basic_ops ends up indirectly calling OfficialClientManager() which will try to contact nova. But the identity.uri is defaulting to None in the config. So it is novaclient that is logging the error.

The call during import is caused by

class TestServerBasicOps(manager.OfficialClientTest):

    scenario_utils = test_utils.InputScenarioUtils()

I don't think we should be talking to the cloud while doing 'testr list-tests' but I'm not sure of the best way to fix this.

I believe this particular issue has already been fixed. Can you please confirm and close this if it has been fixed.
